Abstract
Description
Technical Field
[0001] This utility model belongs to the field of measuring instrument technology, specifically relating to a circuit board mounting structure and a wired data acquisition device. Background Technology
[0002] Existing wired data collectors are connected to water meters via M-bus (Meter-Bus) to enable data communication between the collector and the water meter. The wired data collectors have internal batteries for power supply, which typically last for 6 to 7 years.
[0003] Both the M-bus and the battery require connection to the circuit board via connecting wires. In existing technology, connecting wires are typically soldered to the circuit board. For soldering the connecting wires to the circuit board, one assembly method involves using additional tooling or a robotic arm to clamp and fix the circuit board for soldering; another method is to place the circuit board on a platform and solder the connecting wires to it. However, this results in longer connecting wires, increasing material costs and placing higher demands on wiring control.
[0004] Therefore, there is an urgent need to propose a circuit board mounting structure that facilitates the connection between the connecting wire and the circuit board, as well as a wired data acquisition device to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a convenient mounting structure for connecting wires to circuit boards, as well as a wired data acquisition device. This purpose is achieved through the following technical solution:
[0006] The first aspect of this utility model provides a circuit board mounting structure, comprising:
[0007] The bottom shell has an internal mounting component, which includes a support portion. The top surface of the support portion has a slot, into which the side of the circuit board can be inserted. The top surface of the support portion is used to support the back of the circuit board.
[0008] Using the circuit board mounting structure in this technical solution, when connecting the circuit board to the battery or cable, one side of the circuit board can be inserted into the slot for fixation. At this time, the top surface of the circuit board and the support form a certain angle, which facilitates the connection of the circuit board and cable to the back of the circuit board. After the connection is completed, the circuit board can be placed flat on the support to fix the circuit board and the bottom shell. The support serves to support the circuit board. By integrating the slot into the support, there is no need to use additional tooling or robotic arms, effectively reducing costs and operational difficulty. At the same time, since the slot for fixing the circuit board is located inside the bottom shell, the distance between the circuit board and the cable and battery is closer, which can reduce the length of the connecting wire, reduce material costs, and reduce wiring difficulty. In addition, the mounting component also serves to support the circuit board when fixing it to the bottom shell.
[0009] In addition, the mounting structure of the circuit board of this utility model also has the following additional technical features:

The side of the second buckle facing the bottom shell is an abutting surface, which is used to abut against the front of the circuit board.
[0013] In some embodiments of this utility model, the surface of the second buckle opposite to the abutting surface is an inclined surface, and the inclined surface is inclined from the side wall to the end away from the side wall toward the bottom of the bottom shell, and the inclined surface is a plane or an arc-shaped surface.
[0014] In some embodiments of this utility model, the mounting component further includes a limiting part, which is connected to the supporting part. The top surface of the limiting part is higher than the end surface of the supporting part. The circuit board can be placed between the two limiting parts, and the sides of the two limiting parts facing away from the circuit board are respectively connected to the second side wall and the third side wall.
[0015] In a second aspect, this utility model provides a wired data collector, which includes a circuit board, a cable, a battery, and a mounting structure for the circuit board as described in the above embodiments. The cable is connected to the side wall of the bottom shell, the battery is disposed inside the bottom shell, the cable is electrically connected to the back of the circuit board via a first connecting line, the back of the circuit board is supported on the end face of the support portion, the back of the circuit board and the bottom shell form a cavity for placing the battery, the battery is electrically connected to the back of the circuit board via a second connecting line, and during the connection process between the circuit board and the first connecting line and the second connecting line, the circuit board is inserted into the slot.
[0016] In some embodiments of this utility model, a sealant is provided inside the bottom shell, and the sealant is located on the front side of the circuit board.
[0017] In some embodiments of this utility model, the wired collector further includes a transparent cover, which is disposed on the top of the bottom shell, and the outer periphery of the transparent cover is connected to the side wall of the bottom shell.
[0018] In some embodiments of this utility model, the cavity is provided with a filler, which is used to restrict the movement of the battery. Attached Figure Description

[0031] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof.

[0032] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence.

Figure 2 schematically shown Figure 1 Enlarged view of point A in the middle. Figure 3 A schematic diagram of the structure of the bottom shell 100 according to an embodiment of the present invention is shown. Figure 4schematically shown Figure 3 Enlarged view of point B in the middle. Figure 5 A partial structural diagram of a wired data acquisition unit (after circuit board 200 is installed) according to an embodiment of the present invention is shown schematically. See also Figure 1 to Figure 5 This utility model proposes a circuit board mounting structure, including a bottom shell 100, and a mounting component 110 is provided inside the bottom shell 100. The mounting component 110 includes a support part 111, and a slot 111c is provided on the top surface of the support part 111. The side of the circuit board 200 can be inserted into the slot 111c, and the top surface of the support part 111 is used to support the back of the circuit board 200.
[0035] Using the circuit board mounting structure in this technical solution, when connecting the circuit board 200 to the battery 400 or the cable 300, one side of the circuit board 200 can be inserted into the slot 111c for fixation. At this time, the top surface of the circuit board 200 and the support 111 forms a certain angle, which facilitates the connection of the circuit board 200 and the cable 300 to the back of the circuit board 200. After the connection is completed, the circuit board 200 can be placed flat on the support 111 to fix the circuit board 200 and the bottom shell 100. The support 111 serves to support the circuit board 200. By integrating the slot 111c into the support 111, there is no need to use additional tooling or robotic arms, effectively reducing costs and operational difficulty. At the same time, since the slot 111c for fixing the circuit board 200 is located inside the bottom shell 100, the distance between the circuit board 200 and the cable 300 and battery 400 is closer, which can reduce the length of the connecting wires, reduce material costs, and reduce wiring difficulty. In addition, the mounting part 110 plays a supporting role for the circuit board 200 when fixing the circuit board 200 and the bottom shell 100.
[0036] Optionally, the cable 300 is connected to the side wall of the bottom shell 100 via a plug-in connection. The cable 300 is connected to the circuit board 200 via a first connecting wire 310. The battery 400 is located on the top of the bottom shell 100, and after the circuit board 200 is installed, the battery 400 is located below the circuit board 200. The battery 400 is connected to the circuit board 200 via a second connecting wire 410. Optionally, both the first connecting wire 310 and the second connecting wire 410 are connected to the circuit board 200 by soldering. It should be noted that the front of the circuit board 200 refers to the side containing the circuit components, and the back of the circuit board 200 has solder joints, mounting holes, etc., which can be used for connecting the connecting wires.
[0037] Furthermore, the support portion 111 includes a first support plate 111a and a second support plate 111b. Both the first support plate 111a and the second support plate 111b are arranged along the height direction of the bottom shell 100 and are perpendicular to each other. The bottom of the first support plate 111a and the bottom of the second support plate 111b are respectively connected to the bottom shell 100. The top surface of the first support plate 111a and the top surface of the second support plate 111b are used to support the back of the circuit board 200. The slot 111c is provided on the top surface of the first support plate 111a.
[0038] Understandably, by vertically arranging the first support plate 111a and the second support plate 111b, the contact area between the support portion 111 and the circuit board 200 can be increased, allowing the circuit board 200 to be stably placed on the support portion 111. In some embodiments, one side of the second support plate 111b is connected to the middle of the first support plate 111a, and the top surface of the support portion 111 is T-shaped. In other embodiments, the first support plate 111a and the second support plate 111b can also be vertically intersecting, so that the top surface of the support portion 111 is cross-shaped.
[0039] Preferably, the width of the slot 111c is the same as the thickness of the circuit board 200, and the depth of the slot 111c is sufficient to fix the circuit board 200 and prevent it from wobbling. The circuit board 200 and the slot 111c can have a transition fit or an interference fit. Optionally, the circuit board 200 is inserted into the slot 111c in a vertical direction, that is, after the circuit board 200 is inserted into the slot 111c, the circuit board 200 is set vertically and perpendicular to the bottom surface of the base shell 100. In this position, the circuit board 200 has sufficient space to connect with the connecting wire, while avoiding excessively long connecting wires and increased wiring difficulty. Of course, in some embodiments, the axial direction of the slot 111c can be tilted, and the circuit board 200 is inserted into the slot 111c in an tilted position. By increasing the angle between the circuit board 200 and the bottom plate of the base shell 100, the connection between the circuit board 200 and the connecting wire can be made more convenient, but the length of the connection needs to be appropriately increased. In the actual production process, the slot 111c structure can be set according to specific operational requirements so that the circuit board 200 is fixed at an appropriate angle and with the support 111.
[0040] Furthermore, the bottom shell 100 has a first sidewall 102, and two mounting members 110 are provided, which are symmetrically arranged about the central axis of the first sidewall 102.
[0041] Understandably, by providing two mounting members 110, the connection stability between the circuit board 200 and the slot 111c can be increased. The symmetrical arrangement of the two mounting members 110 provides balanced support for the circuit board 200, preventing it from tilting. Of course, in some embodiments, the number of mounting members 110 can be one, three, four, or five, etc. When there are two or more mounting members 110, adjacent mounting members 110 are spaced equidistantly, thereby increasing the connection stability between the circuit board 200 and the mounting members 110. Optionally, a stepped portion 150 is provided along the inner periphery of the bottom shell 100, and the bottom of the mounting member 110 is connected to the top of the stepped portion 150.
[0042] Further, see Figure 3 The bottom shell 100 has a second side wall 103 and a third side wall 104 arranged opposite to each other. The second side wall 103 and the third side wall 104 are respectively connected to the two sides of the first side wall 102. A first buckle 120 is provided on the inner side of the first side wall 102. The circuit board 200 can be snapped between the first buckle 120 and the support part 111. A second buckle 130 is provided on the inner side of both the second side wall 103 and the third side wall 104. The side of the second buckle 130 facing the bottom shell 100 is the abutment surface, which is used to abut against the front of the circuit board 200.
[0043] Optionally, the mounting component 110 is positioned close to the first sidewall 102, allowing the circuit board 200 to be tilted and engaged between the first latch 120 and the mounting component 110 (tilt angle between 10° and 60°). When fixing the circuit board 200 to the base shell 100, the circuit board 200 is first tilted and inserted between the first latch 120 and the mounting component 110. At this time, the side of the circuit board 200 away from the first latch 120 is tilted upwards, and the tilted side is pressed downwards, causing the circuit board 200 to engage with the second latches 130 on both sides. Thus, through the support of the support part 111 and the abutment of the first latch 120 and the second latches 130, the circuit board 200 can be stably fixed to the base shell 100. Optionally, a notch 210 is provided at one corner of the circuit board 200 on the side away from the first latch 120, through which the installation direction of the circuit board 200 can be easily determined. Correspondingly, the interior of the bottom shell 100 is provided with a protrusion 160 corresponding to the notch 210.
[0044] Optionally, the first support plate 111a is connected to the first sidewall 102, and the two second support plates 111b are connected to the second sidewall 103 and the third sidewall 104, respectively. By adopting this structural form, the structural strength of the mounting component 110 is increased, thereby making the overall structure more stable and reliable.
[0045] Furthermore, the surface of the second buckle 130 opposite to the abutment surface is an inclined surface. The inclined surface slopes from the side wall to the end away from the side wall toward the bottom of the bottom shell 100. The inclined surface is a plane or an arc-shaped surface.
[0046] Understandably, during the installation of circuit board 200, the side of circuit board 200 comes into contact with the inclined surface. Setting this surface at an inclination can avoid problems such as jamming or interference during the installation of circuit board 200.
[0047] Further, see Figure 4 and Figure 5 The mounting component 110 also includes a limiting part 112, which is connected to the support part 111. The top surface of the limiting part 112 is higher than the end surface of the support part 111. The circuit board 200 can be placed between the two limiting parts 112. The sides of the two limiting parts 112 that are away from the circuit board 200 are respectively connected to the second side wall 103 and the third side wall 104.
[0048] The limiting part 112 restricts the movement of the circuit board 200, preventing it from sliding off the support surface and falling below the bottom shell 100. Optionally, the limiting part 112 is a plate-shaped structure connected to the side of the second support plate 111b away from the first support plate 111a. Understandably, the spacing between the two limiting parts 112 is set according to the width of the circuit board 200, ensuring that the circuit board 200 can be installed between the two limiting parts 112 while preventing excessive offset of the circuit board 200.
[0049] Furthermore, Figure 6 An exploded view of a wired data acquisition device according to an embodiment of the present invention is shown schematically. Figure 7 A schematic cross-sectional view of a wired data acquisition device (with two batteries 400 disposed in cavity 101) according to an embodiment of the present invention is shown. Figure 8 A schematic cross-sectional view of a wired data acquisition device (with a battery 400 disposed within the cavity 101) according to an embodiment of the present invention is shown. See also Figure 6 to Figure 8 This technical solution also provides a wired data acquisition device, including a circuit board 200, a cable 300, a battery 400, and an installation structure for the circuit board. The cable 300 is connected to the side wall of the bottom shell 100, and the battery 400 is disposed inside the bottom shell 100. The cable 300 is electrically connected to the back of the circuit board 200 through a first connecting line 310, and the battery 400 is electrically connected to the back of the circuit board 200 through a second connecting line 410. The back of the circuit board 200 is supported on the end face of the support part 111. The back of the circuit board 200 and the bottom shell 100 form a cavity 101 for placing the battery 400. During the connection process between the circuit board 200 and the first connecting line 310 and the second connecting line 410, the circuit board 200 is inserted into the slot 111c.
[0050] By setting an mounting component 110 inside the bottom shell 100 to assist in the installation of the circuit board 200 and the connecting wires, and to assist in the fixation of the circuit board 200 and the bottom shell 100, the installation of the circuit board 200 is more convenient. There is no need to use additional tooling to fix the circuit board 200, and there is no need for long connecting wires, which effectively saves production materials.
[0051] Optionally, the inner wall of the bottom shell 100 is provided with a plurality of third buckles 140, and the outer periphery of the top cover 600 is provided with an extension 610, on which a locking hole 611 is provided. The top cover 600 and the bottom shell 100 are engaged with the third buckles 140 through the locking hole 611.
[0052] Further, see Figure 8 The bottom shell 100 has a sealant 800 inside, which is located on the front of the circuit board 200. By filling the bottom shell 100 with sealant 800, the bottom shell 100 can meet the waterproof requirements.
[0053] Further, see Figure 7 The wired collector also includes a transparent cover 500, which is placed on top of the bottom shell 100 and the outer periphery of the transparent cover 500 is connected to the side wall of the bottom shell 100.
[0054] The transparent cover 500 protects the components and circuits inside the base shell 100. Optionally, the transparent cover 500 has connecting posts at both ends, with mounting holes inside the connecting posts. The base shell 100 has a connecting shaft inside, and the connecting posts are interference-fitted with the connecting shaft through the mounting holes, thereby enabling the installation of the transparent cover 500 and the base shell 100.
[0055] Optionally, the cavity 101 is provided with a filler 700, which is used to restrict the movement of the battery 400.
[0056] See Figure 7 and Figure 8In this technical solution, the cavity 101 can accommodate two batteries 400. When there are two batteries 400, the filler 700 is not needed. When there is only one battery 400, the filler 700 fills the cavity 101 to prevent the battery 400 from moving. Furthermore, the filler 700 reduces the amount of glue used, saving on glue costs. This approach improves the applicability and compatibility of the wired data acquisition device. Optionally, the filler 700 can be made of foam. Foam has a certain degree of elasticity, preventing excessive pressure on the components inside the cavity 101, and it can be interference-filled into the cavity 101. The interference filling prevents the foam from loosening. Optionally, the cross-section of the foam forms an isosceles right triangle, with one right-angled side fitting against the side wall of the bottom shell 100 and the other right-angled side fitting against the back of the limiting plate. The isosceles shape of the foam facilitates installation and prevents the circuit board 200 from being squeezed after being installed backwards.
[0057] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope of the claims.
